Submerge Question


#1

I get that troops Avoid AoE when they are submerged, but how exactly is that handled when it comes to “damage randomly split between troops” spells?

Eg:
My Opponent has 3 of his 4 troops submerged.
I cast a Spell that does 40 damage randomly split between troops.
Now obviously 3 of the troops are going to take 0 damage but what about the 4th?
Will he take the full 40 damage, or has a portion of that been wasted missing the submerged troops?

Another way to put it, Which of these is correct?:
a) Since three troops are submerged (and cant be seen) the random damage is split between the only visible troops (1)
b) Damage is split between all 4 troops just as it would be if no one was submerged and damage is “wasted” on the water the troops are submerged under.


#2

I think it’s randomly split still. Makes sense.


#3

Damage that “randomly splits amongst enemies” actually targets all enemies which is why submerge will protect against it.


#4

But one single non submerged troop won’t get the full damage, just a percentage of it?
